Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Mix the baking powder with the flour.
Add the flour and water alternately to the butter mixture.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Bake and finish
Divide the batter into three layers and bake until golden.
Cool and frost as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy structure to the batter.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking, helping the layers rise.
- White sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
The step that matters
Gently fold the egg whites into the batter. Whipped egg whites hold air that gives the cake its lift. Stirring vigorously knocks that air out, so the layers can come out dense and flat.
